I have a set of 1972 Buick GS 455 Stage 1 Cylinder Heads for sale. I dont have a lot of background information on these heads but here is what I do know: The heads have Casting Number #1238148 with date stamps of M8 and M16 which translates to the dates December 8, 1971 and December 16, 1971, respectively. The valves are Stage 1. One of the intake valves is worn at the rocker arm end. There must have been a rocker arm go bad or a rocker arm retainer come off. I dont have a close up picture of this valve top, but I will take a picture and post it later tonight. The heads have the Nylon valve seals installed. The heat cross-over passages to the intake for the choke have been plugged off. Horrible paint job match to the original 1972 Buick Red engine color. I will also take a close up picture of the cross-over passages and the valves as well and post them later tonight. Price is $250 for the pair plus shipping.
Mike, I just added three more pictures to the original post. Also, as I mentioned earlier, I am about 20 miles from Detroit and I am also about 6 miles from DTW (Detroit Metro Airport) in Romulus, if that helps. Okay, as of right now: "Mike Sobotka" is first in line. "Ramkat2" is second in line. "eganddg" is third in line. Thanks,
